NAME
cgD3D9SetSamplerState - set the state associated with a sampler parameterSYNOPSIS
#include <Cg/cgD3D9.h>
HRESULT cgD3D9SetSamplerState( CGparameter param, D3DSAMPLERSTATETYPE type, DWORD value );
PARAMETERS
- param
- The sampler parameter whose state is to be set.
- type
- The D3D sampler state to set.
- value
- A value appropriate for type. See the D3D documentation for appropriate values for each valid type.
RETURN VALUES
Returns D3D_OK if the function succeeds.Returns the D3D failure code if the function fails due to a D3D call.
DESCRIPTION
cgD3D9SetSamplerState sets the state associated with a sampler parameter.EXAMPLES
// param is a CGparameter handle of type sampler ... // Set this sampler for tri-linear filtering cgD3D9SetSamplerState(param, D3DSAMP_MAGFILTER, D3DTEXF_LINEAR); cgD3D9SetSamplerState(param, D3DSAMP_MINFILTER, D3DTEXF_LINEAR); cgD3D9SetSamplerState(param, D3DSAMP_MIPFILTER, D3DTEXF_LINEAR);
ERRORS
cgD3D9Failed is generated if a D3D function returns an error.CGD3D9ERR_INVALIDPROFILE is returned if params's profile is not a supported D3D profile.
CGD3D9ERR_NODEVICE is returned if a required D3D device is NULL. This usually occurs when an expanded interface routine is called but a D3D device has not been set with cgD3D9SetDevice.
CGD3D9ERR_NOTLOADED is returned if program was not loaded with the cgD3D9LoadProgram.
CGD3D9ERR_NOTSAMPLER is returned if param is not a sampler.
CGD3D9ERR_NOTUNIFORM is returned if param is not a uniform parameter.
CGD3D9ERR_INVALIDPARAM is returned if the parameter fails to set for any other reason.
